WiFi Signal Strength Meter
Build a Portable WiFi Signal Strength Meter with ESP8266 & OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn an ESP8266 into a handheld WiFi scanner that shows live signal strength on a crisp OLED screen. Walk around your home or school, watch the SSIDs pop up and their RSSI bars grow or shrink — a perfect tool for understanding wireless coverage and building your first IoT gadget.
What You'll Build
A compact, USB-powered device that continuously scans for WiFi networks and draws a real-time bar graph of signal strength for each one. You'll see network names (SSID) and how strong each is in dBm, letting you spot dead zones, compare router positions, or even hunt for open networks — all from a project you build yourself.
What You'll Learn
- Program an ESP8266 to perform WiFi network scans and extract SSID/RSSI data
- Display custom graphics and live bar graphs on an I2C OLED screen
- Wire components on a breadboard and understand I2C communication protocols
- Interpret RSSI values and grasp the basics of wireless signal propagation

Who This Kit Is For
Designed for curious young minds in ATL Tinkering Labs, CBSE middle‑school projects, and family maker sessions. If you’re a student from Class 6–10 building a science fair exhibit or a parent introducing electronics to your 10‑year‑old, this kit offers a friendly, hands‑on dive into wireless networks — no prior coding required.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?

What does RSSI mean and how is it shown?
RSSI (Received Signal Strength Indicator) is a number in dBm that tells how strong a WiFi signal is. On the OLED, each network gets a horizontal bar — the longer the bar, the stronger the signal. You’ll see the SSID and the bar update live as you move around.
Can I use this to improve my WiFi at home?
Absolutely. Carry the meter to different rooms and watch which networks lose bars. It’s a visual way to find dead zones and test if moving your router helps.
Do I need to write code from scratch?
No. The kit includes ready‑to‑upload code that handles all the scanning and graphing. You’ll learn how the ESP8266 works, but coding experience is not required to succeed.
ESP8266 scans all nearby WiFi networks and displays SSID and RSSI bar graph on OLED.
